Made at our plant in Huizhou since 2016. PET runs hot and dries hard, so the carrier has to be PET-matched: a PE-based black in a PET line is the usual cause of breaks in spinning and haze in sheet.
PET processing has two things the grade has to respect: drying before processing, and the temperature window. Both rule out a general-purpose polyolefin carrier.
| Carrier resin | PET (matched to your PET grade and IV) |
|---|---|
| Carbon black content | Set by the depth of shade and opacity you need |
| Standard grades | PET1832 (PET carrier) — see the full TDS chart |
| Dispersion | Fine — critical for fine-denier fiber and clear-adjacent sheet |
| Drying guidance | Supplied with the grade, since PET must be dried before processing |
| Melt behavior | Matched to your spinning or extrusion temperature window |
| Certifications | ISO 9001 / 14001 / 45001 |
Tell us your PET grade, denier or sheet thickness, and line — we will match a carrier and send sample.
The carrier matches your polymer, which is what prevents spinning breaks and haze.
Shade consistency between lots matters when your customer reorders the same fabric or sheet.
No trading-company layer. A firm factory quote and a technical answer from the compounder.
Run a trial on your own line before you commit. We keep your spec confidential.
Typical PET applications our black masterbatch is compounded for:
Black polyester staple for textiles and nonwovens.
Carpet yarn and industrial filament.
Black sheet for thermoformed trays and blisters.
Black strapping for pallet and bale securing.
PET is the least forgiving polymer for masterbatch, and almost none of the difficulty is about colour. Three points decide whether a PET black grade works:
| You are making | Typical let-down | What to specify beyond “black” |
|---|---|---|
| Staple or filament fibre | 1–3% | Dispersion (filter pressure value), moisture, PET-compatible carrier |
| Strapping | 2–4% | Colour depth plus strength retention after loading |
| Sheet and APET | 2–5% | Surface appearance — dispersion shows up as texture at this thickness |
| Bottle-grade or rPET streams | 2–4% | Carrier and IV contribution, ash content |
If you tell us the line and the target IV, we will propose a carrier and loading rather than send a generic black. The PET gels and filter pressure guide covers how to isolate a masterbatch fault from a drying fault, and the carbon black content testing note covers how to verify the loading you paid for.
We do not recommend it. A polyolefin carrier in PET is a common cause of spinning breaks, haze in sheet and inconsistent shade. Use a PET-carrier grade instead.
Yes, like any PET material. We supply drying guidance with the grade so your operators have the parameters on hand.
Trial lots start at 1 ton per specification, enough for a spinning or sheet trial. We quote trial and production quantities on separate price points.
Typically 5–10 days to most markets, with drying and let-down guidance for your line.
Tell us what you are running and how much you need. We reply with a firm factory quote — and, if you want to test before committing, a free 1–5 kg sample compounded on your own carrier resin. No obligation.
PET black masterbatch is easy to under-disperse and hard to hide. This is the compounding line and the QC lab.
